Types

Type	Description
AlgebraNotImplemented	Raised when an Algebraic case is found in FastSim which has not been implemented, or does not make sense to implement.
BinaryOp
Bit	Binary data used in simulation
ComparisonOp
FSInterface
FastAlgExp
FastBits
FastData
JSCanvasState	State retrieves directly from Diagram has Javascript objects
JSComponent	Wrapper for Javascript (Diagram) component. Why here?
JSConnection	Wrapper for Javascript (Diagram) connection. Why here?
PortRmInfo
SimulationComponent	Like Component but with additional dynamic info used by simulator Clocked components have state data. All components have optional data on inputs that propagates During evaluation of combinational logic Components require all inputs to have data before they can generate output data Note that reducer is a function that generates the outputs TODO: make this equatable data?
SimulationComponentState	State (possibly none) remembered by component from previous clock cycle. Combinational components have no state.
SimulationError	- Documents an error found while simulating. - Should never happen
SimulationErrorType
SimulationGraph	Map every ComponentId to its SimulationComponent.
SimulationIO	For every IO node, keep track of its Id, Label and wire width. - Id: to feed values into the simulationGraph. - Label: to display a nice form to the user. - Width: to feed the right values into the simulation.
UnaryOp
WireData	Fixed width bus data used in simulation TODO: refactor as bigint for efficiency The list is little-endian: the LSB is at index 0, and the MSB is at index N-1, where N is the length of the list.
